# Protoc Gen ArkTS > !NOTE > Forked from [protoc-gen-ts](https://github.com/thesayyn/protoc-gen-ts) Compile `.proto` files to plain `ArkTS`. Supports concurrent with `@Sendable` on codec classes. Run with [`@ohos/protobufjs`](https://ohpm.openharmony.cn/#/cn/detail/@ohos%2Fprotobufjs) ## Features - Passes all required conformance tests - **Supports ArkTS(ets)** with `@Sendable` for concurrent - Supports well-known types - ~~Supports json encoding (`toJson`, `fromJson`)~~ - Supports binary encoding (`toBinary`, `fromBinary`) - Optimized for [de]serialization speed. ## Usage ```sh npm install -g @larkoh/protoc-gen-ets ``` ### Protoc ```properties protoc -I=sourcedir --ets_out=dist myproto.proto --ets_opt="namespace_as_file=true,export_indcies=true,bigint_as_long=true" ``` ## Development ```sh ./infra/test.sh ```
